:BAG EAsrENER.

Application med-December 3,1920. YSerial'No. 427,945.

To all whom' t 'may concern i Be it known that I, FRANZ A. FULLER, acitizen of the United States, residing in Newark, in *thel county ofEssex andV State l`of New Jersey, have invented vcertain new and usefulImprovements in Bag Fasteners, 'of which the followingis aspecification.

This invention has as` its main object to provide abag fastener wherebythev two metal side frames of the bag may be either4H temporarily'securedin engagement' by'spring actuated bolt devices readilylrelea'sed by hand, orl positively locked in such manner 'as to'require4a key inorder to separate the same in obtaining ,accessto the bag.

Afurther object is toprovide av neat and attractive ty e of bag fastenercomprised of'fewand simple parts, cheaply constructed' and readilyapplied.

These and other analogous objects are vattained by the novelco'nstructiomcombination and arrangements of kparts herein. yafterdescribed and shown in the accompanying drawings forming a materialpart` of' this disclosure, and in which 1'- 'Figiire l 1s a fragmentaryvside elevational view of a conventional type of bag showing a fastenermade inl accordance` wth the invention in operative position.

A capj'pieceBO:alsohollow and smaller in n' length and width is slidablymounted on the casing, this cap having a transverselycurvedtopfeXcept-'at its raised flat. centerv y31 which has an expandedcentral socket 32;

,Soldered or otherwise vsecured `within the plate 2O conveying linealmotion tothe saine and "fat ythe same timeslidably securing thelcap'andpla'te Btothe casing. g

i lThe plate .35 isfor'medwit-hraised angl-1'; i

larly lturned edgesj36" and .36` serving as tain than in a'lacked-position..

Formed. inthe plate 35 are two raised elei mentsl 8y adapted yLto reduce`thearea in '.fri'cn tional` contact',with the plate 20 and 'midr` yway`in itslength, to one side-jef the center vis' a single raised stop 39yadapted to make contact/'with' thel ends of the openings 27 ico A postor stud 40 extends slightly above the cap element 3l, through which,together with the reenforcement 34, it passes.

The upper end of the post contains an aXial bore 4l and a cross slot 42,the former being receptive of the point 43 of the key 45, the broadenedportion 44 of which engages the slot 41 while the nibs 46 prevent thekey from entering an undesirable depth.

At the inner end of the post is a flange 48, between which and the`plate 34 is a 'compression spring 49 encircling the post,

Y' tending` to press the flange 4S towards the plate 20;

Formed on the outer surface of the flange is afrectangular lug 50 having.straight yparallel sides extending from the center to the@ periphery ofthe flange in alignment with the slot 41.

.Extending from the lug axially of the post, is a pivot 51, the samepassing through a guide opening appropriately formed in theplate 35. f

' Another compression spring 52 is disposed within the cap, extendingfrom one end to the prong 26 byy which it is maintained in operativeposition, this spring acting to press the cap into engagement with thestop 39 `causing the cap and, casing to normally register but-permittingthe cap to be moved at such times as the lug 50 is turned into theposition shown in Figure 2.

`Then-it is desired to lock the` bag, the

' key is inserted and the post rotated, bringing the lug into theposition shown in Figure 3, this turning of the post causing the lug 50to rise-as it passes over the top of the stop 39, against the spring 49,the opening 27 tpermitting the lug to be turned forward or back through180-degrees only.

' Obviously when the parts are in the posii tion shown inFigure 3, thatis the outer end carried by it cannot be moved lengthwise of they lugbeing inv-contact with the straight wall of theopening 27, at its lefthand end as illustrated, the cap and parts of the easing into thepositionshown by the broken lines in Figure 2 and the bag is effectivelylocked'against intrusion.

lt will be equally apparent that when the position of the lugy isreversed the parts can be moved against the force of the spring 52,

permitting the catches 17 to be withdrawn from engagement iwith `thesliding bolt eleonly', and notlas restrictive'or.limitative ofy the-invention, 'of which .obviously an embodimentmay be1 constructedincluding many minor modifications without departing from the generalscope herein indicated and denoted in the appended claims.

Having thus described my invention, what l desire to secure by LettersPatent is l. A bag frame fastener comprising an elongated casingprovided with an internal cam in the top wall thereof fiXed to one ofthe frames, a bolt element slidable therein, means in said casing fornormally projecting the bolt in one direction, a catch carried by theother of said frames, said catch being engageable with said bolt, andkey operated means engageable with said internal cam in said casingadapted to confine said bolt, 80

when in one position and to release the bolt when in another position.

2.
